Hello guys, in December my sunroof suddenly stopped working. Since then, I have bought new sunroof motor - 4A0959591C (which is not cheap), I have also bought new sunroof control (Also pretty expensive toy) and it still doesn't even beep. There is no movement from the sunroof motor, nor any sounds. I have tried to measure voltage, that is going to the power connector and there are 4 pins, where on pins 1,3 and 4 and that went fine (Pin 1 - 12.7V; Pin 3 - 12.0V; Pin 4 - 11.06V), therefore I suggest the input power is "okay"? Can anybody please help me? I did not manage to find Sunroof relay, (it has to b e somewhere in the car since my sunroof motor comes without it) and Iam already feeling lost. I tried 2 motors together with 2 controls (all used but in great condition) and still no idea what could be the cause. I have checked the fuse and also replaced it.

I have A6 C4 2,5TDI Quattro - 97'
